I recommend Do More Great Work to my biz coaching clients. While easy to read and understand, the deceptively simple exercises are very challenging and powerful. And very revealing.
I do this stuff for a living, yet found myself picking up this book again and again to work through the exercises for myself. It stayed in the place of honor on the corner of my desk for a couple of months and I would pick it up during the day to do a bit more work and reflect on how Michael’s message related to how my day was going.
I also found it most useful to read through front to back first, ponder the message, then go back, thoughtfully, and take the exercises one at a time as I was ready to take in the implications. This is not something you read and forget, but a tool you can use long term, over and over again, as you craft your future.
